Timing Belt: Adjustments

1. Remove timing belt front upper cover.
2. Carefully check the timing belt on its whole circumference for cracks and peeling.
3. Turn crankshaft in normal direction (clockwise) until timing mark on camshaft sprocket is aligned with mating mark on cylinder head, so that piston in No. 1 cylinder is placed at top dead center on compression stroke.

CAUTION: Do not turn crankshaft in opposite direction (counterclockwise) to align the timing mark with mating mark, otherwise an improper timing belt tension could result.

Timing Marks:

4. Turn crankshaft in normal direction (clockwise) until second tooth past timing mark (punch) position on camshaft sprocket should be aligned with timing mark on cylinder head.

Access Cover Location:

Removing Access Cover:

5. Remove two access covers. Access cover can be easily removed by inserting screwdriver into groove from direction of embossed arrow and pry.
6. Insert wrench through adjusting hole and loosen timing belt tensioner tightening bolt and nut.

CAUTION: Loosen bolt and nut 180 to 200°. If they are loosened more than necessary, they might fall into cover.

7. Insert plain screwdriver from top of timing belt cover. Slightly push tensioner bracket in tensioning direction, and then release. Now belt tension will be automatically adjusted by tensile strength of tensioner spring.

CAUTION: The purpose of pushing tensioner with screwdriver is to loosen tensioner mounting surface which might have stuck due to many hours of being tightened

8. First tighten tensioner mounting bolt (bottom side) with wrench and then tighten mounting nut (top side).

CAUTION: Make sure that bolt (bottom side) is tightened first. If nut is tightened first, belt tension will vary (will become too tight).

Mounting Access Cover:

9. Mount two access covers to respective adjusting holes. Access cover can be easily mounted by sliding in such a way that hook will pass between guide projections.
10. Install timing belt front upper cover.
